data-engineering-zoomcamp
Data Engineering Zoomcamp is a free 9-week course on building production-ready data pipelines. The next cohort starts in January 2026. Join the course here ๐๐ผ
Also, I donโt know if you have come across this but there is a free data engineering course available from DataTalksClub going over some GCP features, Terraform, Docker, Spark, Airflow, and more. I found it great to get a feeling of how all these tools interact.
